The Defense Advanced Research Projects Agency (DARPA) has demonstrated solid-state optical phased array technology in a microchip, bringing the ability to bend light to the battlefront. Share on ...

Chip-scale silicon photonics optical phased array (OPA) is widely used in free-space communication. However, due to the limitation of optical device design and manufacture, the distance between ...

In three recent papers, engineers report the first demonstration of optical phased array technology on-chip at both near infrared and blue wavelength with applications in a broad range of research ...

New York, NY--March 19, 2020--While beam steering systems have been used for many years for applications such as imaging, display, and optical trapping, they require bulky mechanical mirrors and are ...
